To find the speed of a star using Doppler shift, you can measure the change in the wavelength of light emitted by the star. If the light is redshifted, the star is moving away from us; if it is blueshifted, the star is moving towards us. By analyzing the amount of shift, you can determine the star's speed relative to the observer.
Yes, Doppler Radar can be used to find all storms!
Find out the time using speed and acceleration, (time=speed/acceleration) and then use it to find out uniform velocity. From that find out uniform acceleration. (as uniform acceleration is equal changes of velocity over equal intervals of time)
This answer assumes that the reader has a fundantal knowledge of what Doppler effect and Doppler radar are. To be effective, Doppler radar, which is an application of the Doppler effect, must be used with the object moving right at or directly away from the Doppler source. It is possible to use Doppler radar on a target moving at a slant, but the angle of convergence or divergence would have to be known and calculations would have to be made to get a correct answer as to that object's velocity. In an situation where it is used to determine radial velocity, it would be tricky to get it to work in this application. Radial velocity is the movement of an object in a circle or an arc of a circle. If the radial velocity of an object was being was investigated, one could use Doppler radar. But there are some issues. Understand that the object is moving in an arc or a circle, like a ball on the end of a string that is being whirled about. The observer would probably want to stand outside the circumference of the circle. Then a "line of sight" would have to be set up to catch the tangent of the circle so the speed of the object could be sampled in an instant when it was moving directly at or away from the Doppler source. This is possible, but challenging. The radius would have to be measured (if it was not know) and a calculation would have to be made. With the radius of the path of travel measured, and the instantaneous speed discovered via the Doppler radar, a calculation would be rather simple. Note that the radial velocity found would be an instantaneous radial velocity. It the radar unit could not be used to sample an instant when the object was moving right at or directly away from the Doppler source, this would make the calculation really, really difficult. It is still mathematically possible to find an object's radial velocity by measuring the speed of an object that is not moving directly at or away from the source, but it's really, really hard. The angle of the objects path of travel with reference to the direction to the Doppler source would have to be known at the instant the radar imaged its speed. Some calculations could then be made. But it's tough. Certainly if the object under investigation is moving laterally with reference to the radar source (moving directly perpendicular to the line of sight from the radar unit), the source will not be able to see it as it is moving at a right angle to the radar. That means no Doppler effect with which the electronics can work to determine speed. Let's wrap up on this important note. When any object moves in anything but a straight line, its velocity is changing - even if its speed remains constant. That's because velocity is speed with a direction vector tacked on to it. An object moving on a radial path is constantly changing velocity, even if it's just changing direction and moving at a constant speed.
This observation indicates that the Sun is rotating about its axis, causing a Doppler shift in the light's frequency. The difference in frequency between points A and B is due to the Doppler effect, showing that different parts of the Sun are rotating at varying speeds.
You can find the final speed by using the formula: final speed = initial velocity + (acceleration * time). Plug in the given values for initial velocity, acceleration, and time into the formula to calculate the final speed.

Examine the light of hydrogen emissions from a distant galaxy. Compare that spectrum with that of hydrogen in a laboratory. You'll find that spectrum is identical EXCEPT that it is shifted towards longer wavelengths.
Yes, Need For Speed Shift is available for the Wii gaming console. You can find this game at most stores that carry and sell Wii games.
The Eaton-Fuller and Rockwell websites should have them. Google images will be able to find images, as well.. you just put in "8LL shift diagram", "9 speed shift diagram", "10 speed shift diagram", etc.
To find speed using acceleration and time, you can use the formula: speed acceleration x time. Simply multiply the acceleration by the time to calculate the speed.
Normal radar sends out radio waves to determine the location of an object. Doppler radar can not only find the location of an object or storm, but using something known as the Doppler effect can determine how fast it is moving towards or away from the radar.
Yes, Doppler Radar can be used to find all storms!
Perhaps you better ask another question, specifying what you DO have. You do need some information to calculate the speed. You can divide distance / time, or you can use the Doppler effect if you have the specialized equipment.
In most cases, you will find the speed shift sensor for your 1998 Chevy Blazer located on the backside of your transfer case. The transfer case is located on the transmission.
The Doppler effect is used by measuring the change in frequency of waves, such as sound or light, emitted or reflected by a moving object. By comparing the observed frequency with the emitted frequency, the speed of the object towards or away from the observer can be calculated.
